Abstract:
2-substituted benzimidazoles and methods of preparing the same are disclosed. The compositions may include a compound or salt thereof, an acid, and a polar aprotic solvent. The compositions may be used to inhibit corrosion of a metal surface in contact with an aqueous system, and provide enhanced protection against corrosion of metals in the aqueous system.
